I want to upgrade my current NAS (Synology 109j) to something that is expandable and redundant. Last weekend I thought a Drobo with DroboShare would be great! Then I remembered that HP makes a MediaSmart server that runs Windows HomeServer (http://www.shopping.hp.com/product/computer/categories/home_servers/1/accessories/FL700AA%2523ABA). Now I'm stuck. I'm not sure which one I should get. What are your thoughts?
